Lithium Plating Detection: How Virtual Sensors Enable Smarter Fast Charging
Fast Charging Pushes Li-ion Batteries Toward a Hidden Risk Fast charging has become a defining requirement for modern electric vehicles and battery-powered systems. Users expect shorter charging times, consistent performance, and reliable operation under all conditions. For simulation, battery control, and engineering teams, this shift raises a shared challenge: predicting and managing internal battery risk […]
When Agents Build the Model: Accelerating Digital Twins with GT Intelligence Studio
Why Building a Digital Twin Model Still Takes Too Long Our three-part series on physics-based digital twins followed a solar-charged, battery-powered Internet of Things (IoT) monitoring device. We covered the availability and battery-health questions that matter for operating it, how GT-SUITE and GT-AutoLion capture its physics and aging behavior, and how the model runs in […]
Hybrid Powertrain Simulation for a Pickup Truck: How FEV Optimized Five Architectures with GT-SUITE
Most hybrid powertrain programmes commit to an architecture too early. A configuration that looks promising on paper can fall apart once you account for towing loads, payload constraints, and real-world drive cycles simultaneously. By that point, hardware has been ordered and timelines are fixed. FEV North America took a different approach. Working with a 4WD […]
Machine Learning-Based E-Motor Thermal Metamodeling: Replacing FE Models for Fast System-Level EV Simulation
The Challenge with E-Motor Thermal Simulation Thermal simulation of electric motors sits at the intersection of two competing demands: the need for spatial accuracy at the component level, and the speed required for system-level scenario exploration. High‑fidelity 3D Finite Element (FE) thermal models of electric machines are essential for predicting hotspot temperatures, validating cooling strategies, […]
Modeling Hydrogen Fuel Cell Propulsion Systems for Aviation with GT-SUITE
The aviation industry is entering a period of rapid transformation as manufacturers explore new propulsion technologies to meet increasingly ambitious emissions targets. While improvements in conventional engines and sustainable aviation fuels remain important pathways, hydrogen-powered propulsion is emerging as a potential long-term solution for cleaner flights. Among the hydrogen pathways being explored, fuel cell–based propulsion […]
Virtual Validation of Lithium-Ion Battery Management Systems
Battery Management Systems (BMSs) play a critical role in ensuring lithium-ion battery packs operate safely, efficiently, and reliably across all operating conditions. As battery systems become more complex and application demands continue to increase, validating BMS algorithms has become significantly more challenging. Building on the previous blog’s overview of BMS architecture for lithium-ion batteries (LIBs), […]
Solid-State Batteries: Why Virtual Modeling and Simulation are the Only Way Forward
Solid-State vs Lithium-Ion Batteries | What’s Driving the Shift The push for safer, longer-lasting, and higher-energy batteries is accelerating change across the energy storage industry. Solid-state batteries (SSB) are gaining attention as a promising solution to meet these growing demands. Unlike conventional lithium-ion batteries (LIB), which use flammable liquid electrolytes, SSB relies on solid materials, […]
Everything You Wanted to Know About Sodium-Ion Batteries
From Lithium-Ion to Sodium-Ion Batteries: A New Era in Battery Technology As the demand for energy storage continues to rise, sodium-ion batteries (NIBs) are gaining momentum as a compelling alternative to lithium-ion batteries (LIBs). Leveraging more abundant and cost-effective materials, NIBs are especially well-suited for low-speed electric vehicles—where range is less critical and affordability is […]
